dictionary - How do I add different numbers in multiple lines in python? -


so have file 9 different phone numbers. there line every call, , duration. want add duration of calls , match them own phone number.

here part of file:

    7803214567;94     7801234567;602     7801234567;910     7808765432;925     7801234567;631

the first being phone number , second being duration in seconds. more clear, example: 7801234567, want add 602, 910 , 631 , match own phone number 7801234567.

it seems want count total number of minutes each unique phone number.

you use counter:

from collections import counter c = counter()  open("path/to/file.txt", 'r') f:     line in f:         k, v = line.split(";")         c += counter({k: int(v)})  >>> print(c) counter({'7801234567': 2143, '7808765432': 925, '7803214567': 94})

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
